I started a blog earlier asking about the value of different juicers and what people thought of the process. There are good comments and suggestions from respondents, so you might want to check it out. http://www.t-g.com/blogs/stevemills/entry/49403/
I ended up not getting a "juicer", strictly speaking. Instead I went with a blender on steroids, Vitamix. Just to be clear for those who know about "affiliate links", there are none. I am not making anything for mentioning the name. :-)
I chose a blender because it includes the whole fruit or vegetable I am adding, not just the juice. When I started out I visited a number of retail juicers and smoothie stores, because I was undecided which way to go AND I wanted to see what I could actually "stick to" before I invested in equipment.
As I watched my drink be prepared in the juicing establishments. I could not help but notice the "pulp" being discarded and I immediately translated that to "fiber". All the benefits of fiber came flooding into my head and it did not take long for me to drift to the "blending" side.
Then, as I had my smoothies being made in a number of smoothie shops, I kept being asked if I wanted this or that additive and I quickly decided that I just wanted it natural, with no extra powder, etc.
Another thing I decided was to not get extreme about this. Some might think that bringing my mixer, cooler packed with yogurt, and other perishable, along with bags of vegetables into a hotel is getting extreme, I call it dedicated. Extreme to me was drinking smoothies only and going "cold turkey" with all other foods.
I started out replacing one meal a day, then two and now occasionally skip the third if I am just not hungry. I also chose to stay away from gluten (as much as possible), but I will go into more of this as I post more thoughts and let you know what is good and maybe not so good. (Not bad, just different)
